WOIRKHOLDER FOR SWISS EIVIBROIDERY MAUI-LINES.

' Application filed June 20, 1922. Serial No. 569,662.

T 0 all whom it may concern:

Be it known that I, ALBERT TAYLOR, a subject of the King of Great Britain and Ireland, residing at Belfast, Ireland, have invented certain new and useful Improvements Relatin to IVorkholders for Swiss Embroidery ll achines, of which the following is a specification.

This invention relates to workholders for embroidery machines, its object being to provide improvements therein.

Under this invention, the work-holder, which is made in the well-known corner angle shape whereby the angled back of one holder fits into the angled front of the holder behind so that the holder takes up the least possible space for a maximum of area available for the embroidery work on the articles held by the work-holder, is characterized by an open angular frame of suitable material, having its inner edge grooved, and provided with means whereby it can be attached to the machine frame. In combination with this grooved angular frame is provided a device which can fit into the groove of the frame for the purpose of holding an article under tension between it and the frame and has means whereby it can be expanded to fit into the grooved frame, and also be contracted to permit of its removal therefrom, when required.

The invention will now be described with,

reference to the accompanying drawings whereon Fig. 1 is an elevation of part of an em broidery machine showing a number ofwork holding devices in accordance with my invention.

Fig, 2 is a plan view of a single Work holding device of the construction illustrated at Fig, 1,

Fig. 3 is an elevation of part of another form of work holding device in accordance with the invention.

Fig. 4 is a plan view of the form of the device shown in Fig. 8. I

Referring to the drawings As illustrated at Figs. 1 and 2,each' of the work-holding devices comprises an open angular frame 1 having a grooved lnner edge 2. In combination with this angular frame 1 is provided a device consisting of two angular members 3 and 4 connected together at their ends and which together form a shape similar to the angular frame 1.

The angular members 3 and at are covered with rubber, or equivalent, 5, and they are connected at their otherwise free ends with levers 6 by means of which the ends can be moved away from each other to expand the members 3 and 4' so that they will fit tightly into the grooved frame 1. The levers 6 arealso used to draw the ends towards each other in order to contract the members 3 and 4 to allow of their withdrawal from the frame 1, when desired.

The arrangement is such that the article to be held by the device is placed in position over the frame 1 and the previously contracted angled members 3 and 4' are placed in position ready to be expanded to fit into the grooved edge of the frame, so that, when so expanded, the article will be held thereby under tension within the frame, by the members 3 and 4.

Figs. 3 and 4 illustrate another method of expanding and contracting the angular members 3 and 4. In this case the ends of the members 3 and 4: are connected with a turnable member 7 which, when turned,

willcause the ends of thelangled members 3 and 4 to be forced apart, or drawn .together, to respectively expand, or contract, the device.

The angular frames 1 are provided with holes 8 through which screws 9 are adapted to pass for securing them to the embroidery machine frame 10.

Other means may be used to force the ends of the angular members apart, or to draw them together, for the purpose of retracting, or expanding, the shape formed by said members, without departing from the nature of this invention.

Having now fully described my invention what I claim and desire to secure by Letters Patent is i A work holding device for use in connection with embroidery machines, com prising an open angular, frame with a fl ll 1,51e,eee
